tax due notice from IRS, CP501, after efile with Turbo Tax 2022

[Chi6]

I just received form CP501 from the IRS stating taxes are due for 2022.  Also stated was interest for unpaid taxes dating back to 5/22/23, however I never received a notice of taxes due after filing. All taxes were paid as calculated by Turbo Tax for the 2022 tax year. The tax due notice does not specify why I owed more taxes that was calculated by Turbo Tax. Do I have any recourse other than to pay the balance requested by the IRS?

I've been to the IRS site and my account. I called the IRS phone number referenced on the notice and the automated system provided a slightly different amount of taxes due. Because it was a weekend call I could not get a live person. Neither the automated system nor my IRS account has any information about why my taxes paid as calculated by Turbo Tax software was inaccurate. I would like to know in what area of the tax return there was an error. It may be possible that there was a missed entry, incorrect amount entered entered, or some other factor that caused this situation. I think it would be helpful to have additional specific information so that this does not repeat in future tax filings.

One thing,  If you had a tax penalty on 1040 line 38 that is only an estimated amount and it is common for the IRS to bill you for more.
